Support pdf files larger than 2Gig.
If FZ_LARGEFILE is defined when building, MuPDF uses 64bit offsets
for files; this allows us to open streams larger than 2Gig.
The downsides to this are that:
* The xref entries are larger.
* All PDF ints are held as 64bit things rather than 32bit things
(to cope with /Prev entries, hint stream offsets etc).
* All file positions are stored as 64bits rather than 32.
The implementation works by detecting FZ_LARGEFILE. Some #ifdeffery
in fitz/system.h sets fz_off_t to either int or int64_t as appropriate,
and sets defines for fz_fopen, fz_fseek, fz_ftell etc as required.
These call the fseeko64 etc functions on linux (and so define
_LARGEFILE64_SOURCE) and the explicit 64bit functions on windows.
